When sufilcient ice has been discharged into the glass, lateralmovement of the glass to the left will simultaneously position the gate2| to close the nozzle and enable the spring means to open the motorcontrol switch and stop the motor.

It is obvious from the foregoing that by the present invention I haveprovided a very simple control mechanism for ice shaving machines whichenables an operator to rapidly and eiiiciently ll the containers withshaved ice and further that the mechanism is so arranged that the motoris only in operation when shaved ice is desired and that the dischargenozzle is only open when there is a container positioned to receive theice therefrom.

While I have shown the preferred form of my invention, itis to beunderstood that various changes may be made in its construction by thoseskilled in the art without departing from the spirit of the invention asdened in the appended claims.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

1. An ice shaving machine of the character described comprising an iceshaving mechanism, an electric motor for operating said mechanism, anozzle through which ice is discharged by operation of said mechanism,an operative gate vcontrolling the nozzle, a switch for controlling themotor, a switch operating mechanism for operating the switch, projectingmeans on said gate adapted to be engaged by a container whereby the gatemay be operated by the positioning and removal of the container fromalignment with the nozzle said gate having a projecting portion, saidswitch operating mechanism lying in the path of movement of saidprojecting portion on the gate whereby opening of the gate will beaccompanied by closing of the switch.

2. In an ice shaving machine of the character described, an ice shavingmechanism, a nozzle through which shaved ice is discharged by operationof the said mechanism, a guide means extending laterally of the nozzleat the discharged end thereof, a closure for said nozzle slidablymounted on said guide for movement into and out of register with saidnozzle, projections pro- Jecting outwardly from said closure and betweenwhich the edge of a container may be interposed whereby the closure maybe actuated by movement of the container laterally of the nozzle.

3. The combination with an ice shaving machine comprising a containerhaving a spout for the discharge of shaved ice, a slidable closuremember for said spout, a pair of lugs extending outwardly from saidclosure member to receive the edge of a receptacle whereby the closuremay be opened and closed by engaging said receptacle with said lugs andmoving the receptacle laterally of the spout, means for shaving ice, anelectric motor for operating said means, and a normally open switchmechanism adapted to be closed by opening of said closure member toplace said electric motor into operation by opening of the closuremember, means on said closure member contacting said switch mechanismwhen said closure is in open position.

4. An ice shaving machine of the character described comprising an iceshaving mechanism, an electric motor for operating the same, a nozzlethrough which shaved ice is discharged by the operation of saidmechanism, an operative closure for said nozzle, an operative controlmechanism for said motor, and means on said closure and controlmechanism enabling the same to be operated together by a container whenthe latter is positioned to receive ice from the nozzle.

5. An ice shaving machine of the character described comprising an iceshaving mehanism, an electric motor for operating the same, a nozzlethrough which shaved ice is discharged by the operation of saidmechanism, an operative closure controlling the discharge of ice throughsaid nozzle, an operative switch operating mechanism for controlling themotor, said closure and said switch operating mechanism being providedwith elements positioned to engage whereby movement of the closure toopen position will be accompanied by operation of the switch operatingmechanism to place the motor in operation.

6. An ice shaving machine of the character described comprising an iceshaving mechanism, an electric motor for operating said mechanism, acontrol switch for said motor, a nozzle through which shaved ice isdischarged by operation of said mechanism, a normally closed gatecontrolling the nozzle, a switch operating mechanism for operating themotor switch and normally tending to maintain said switch open, saidgate and switch operating mechanism being provided with means adapted toengage as the gate is being moved to open position whereby opening ofthe gate will be accompanied by operation of said switch operatingmechanism to close the switch.
